General DescriptionThe SL8411 is an average current mode control LED driver IC operating in a constant off-timemode. SL8411 does not produce a peak-to-average error, and therefore greatly improves accuracy,line and load regulation of the LED current without any need for loop compensation or high-sidecurrent sensing. The output LED current accuracy is ±2%.The SL8411 can be powered from an 8.0 - 100V supply. PWM & Linear dimming input is providedthat accepts an external control TTL compatible signal. The output current can be programmed by aninternal 250mV reference.Features Fast Average Current Control Internal 8 to 100V Linear Regulator Linear and PWM Dimming Capability Output Short Circuit Protection with Skip Mode Requires Few External Components for OperationApplications DC/DC or AC/DC LED Driver Applications LED Street Lighting Back Lighting of Flat Panel Displays General Purpose Constant Current Source Signage and Decorative LED Lighting ChargersTypical Application Circuit
